ABSTRACT:
THE JÖKULHLAUP (GLACIER
BURST) FROM GRlMSVÖTN IN JULY
1954. A PREMLIMINARY ACCOUNT
OF THE INVESTIGATIONS.
After an interval of 6\/v years, since February
1948, a glacier burst from Grímsvötn occurred
in July 1954. Tlie first signs of it were observed
on July 4th. The discharge of Skeiðará increased
unusually slowly and did not culminate until
July 18th. Before the encl of July the hlaup
had ceased. Tliis jökulhlaup xcas accompanied
ég þakka þeirra aðstoð við þessar rannsóknir.
Og síðast en ekki sízt viljum við, sem þátt tók-
um í ofannefndum rannsóknum, Jrakka Oræf-
ingum og þá einkum Ragnari Stefánssyni í
Skaftafelli og hans fjölskyldu, svo og fólkinu á
Fagurhólsmýri, alla þeirra aðstoð og miklu
gestrisni.

by a very intense smell of solfataric gases
which was felt in the remotest parts of the
country. In the vicinity of the hlaup birds
were killed by these „gases and the vegetation,
especially Sorbus aucuparia, was affected. Dur-
ing the jökulhlaup repeated flights were made
over Skeiðarárjökull and Grímsvötn, and for
the first time the discharge of such a jökul-
hlaup was systematically measured. A thorough
report of the investigations, written by S. Rist
and the present writer, will probably be pub-
lishecl in the next issue of Jökull.
